Jeep still working to improve Cherokee's 9-speed auto

Fiat Chrysler is hoping an upcoming software update will stem the tide of consumer complaints surrounding its nine-speed automatic transmission. Owners of the 2014 Jeep Cherokee have reported a number of problems on the National Highway Traffic Safety Administration's SaferCar.gov website, since the new model and its troubled gearbox arrived way back in October 2013. The software update is "intended to keep the vehicle performing as intended, and to prevent durability issues from occurring in the future," an FCA spokesperson told Automotive News, and will be available to owners of both the 2014 to 2015 Jeep Cherokee and the 2015 Chrysler 200, which also uses the 9AT. While FCA will be notifying consumers of the update, owners can also request the software reflash if they happen into their dealer before then. Despite the widely documented problems with the transmission, the only complaints on NHTSA's website relate to the 2014 Cherokee – neither the 2015 Jeep nor the 200 have received any complaints. That bodes well as FCA prepares to begin deliveries of the 2015 Jeep Renegade and launch the Fiat 500X, both of which pair the 9AT with the 2.4-liter Tigershark four-cylinder. "We have had to do an inordinate amount of intervention on that transmission, surely beyond what any of us had forecast," FCA CEO Sergio Marchionne told Automotive News. "There are things that we have done – that we continue to do. Our proactive customer care intervention has actually increased in intensity on these vehicles in 2014, especially in the second half." What's fascinating about the 9AT's problems are that they haven't been the fault of manufacturer ZF, but have related to software that wasn't "mature" and had "teething problems," Marchionne has said previously, AN reports. With the lack of criticism for the 9AT in 2015 models and this pending software update, though, here's hoping that FCA has finally figured out its fuel-sipping gearbox. Related Video:

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Chrysler resolves recall issue with NHTSA, will inspect, upgrade affected Jeeps

Chrysler made big news earlier in the month by refusing a recall request from the National Highway Traffic Safety Administration for the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty. Last week, NHTSA boss David Strickland countered by defending his agency's request for the recall of 2.7 million Jeep SUVs. Today marked the deadline for Chrysler to formally respond to NHTSA, and it seems that both parties have met in the middle with Chrysler inspecting and upgrading some of the affected vehicles without using the word "recall," which would constitute the admission of a defect; instead, Chrysler said that it is conducting a "voluntary campaign."
At issue on these vehicles is the positioning of the fuel tank behind the rear axle that could get damaged during a rear-end collision. NHTSA has stated that at least 51 people have been killed in rear-end collisions involving these Jeeps after the vehicles caught fire, to which Chrysler countered by pointing out that both models "met and exceeded" the requirements for fuel-system integrity.
As a compromise on the situation, Chrysler says that it will inspect all pre-2004 Grand Cherokees and pre-2007 Liberty models and, "if necessary, provide an upgrade to the rear structure of the vehicle." According to Automotive News, this upgrade will consist of adding a trailer hitch that will presumably better protect the rear-mounted gas tank. Vehicles already equipped with a factory or Mopar hitch will not be modified. Chrysler's official statement on the matter is posted below, but no additional information has been released, such as when the campaign will begin and how many vehicles could be affected.
